Computer Fundamentals and System Concepts Questions
-
operating systems
-
test documentation
-
live data
-
user requirement documents
C
Correct answer
Explanation
Configuration Management (CM) controls versioned artifacts like source code, documentation, requirements, test cases, and operating systems - items that need to be tracked, controlled, and audited. Live production data is dynamic and constantly changing; it's not a version-controlled configuration item. CM manages the software and its artifacts, not the runtime data itself.

Computer Aided Design
-
Control Alt Delete (Ctrl - Alt - Del)
C,D
Correct answer
Explanation
CAD primarily stands for Computer-Aided Design, the standard technical term for design software. The Ctrl-Alt-Del association is a humorous/pop culture reference rather than a formal expansion, though the question uses 'refers to' wording which allows broader interpretation.

3;Identification,Environment, Procedure
-
4;Cofiguration, Input Output, File section, Procedure
-
3;Environment, Library, Activity
-
3; Configuration, File section, Procedure
C
Correct answer
Explanation
Easytrieve programs consist of three distinct functional sections: the Environment section (defines system/hardware settings), the Library section (defines files and fields), and the Activity section (contains executable processing logic). Options referencing COBOL-like sections do not apply to the Easytrieve structure.
-
Program or sequence of instructions that is interpreted or carried out by processor directly
-
Program or sequence of instruction that is interpreted or carried out by another program
-
Program or sequence of instruction that is interpreted or carried out by web server only
-
None of above
B
Correct answer
Explanation
A script is a sequence of instructions or a program that is interpreted and executed at runtime by another program, such as a shell or browser interpreter, rather than compiled to machine code and executed directly by the processor. The web server option is too narrow.
-
Use IF ABEND statement in the JCL
-
Use COND
-
Both a and b
-
None
A
Correct answer
Explanation
To trap and conditionally handle abends in JCL, you use the IF ABEND=TRUE statement (or similar syntax depending on JCL variant). This allows conditional execution based on whether an abend occurred. COND is used for job/step condition codes, not specifically for abend trapping. Option C claims both work, but IF ABEND is the direct abend-trapping mechanism. I'm marking this with medium confidence because JCL syntax varies.
-
inetinfo.exe
-
aspnet_isapi.dll
-
aspnet_wp.exe
-
None of the Above
C
Correct answer
Explanation
The actual work process of ASP.NET is handled by aspnet_wp.exe (ASP.NET Worker Process) in IIS 5.x, which executes the ASP.NET code. The inetinfo.exe is the IIS admin service, and aspnet_isapi.dll is the ISAPI extension that routes requests to the worker process. The worker process is where the actual ASP.NET application code runs.

Operating System; Application Programs
-
Hardware; Software
-
Middle Tier; Hardware
B
Correct answer
Explanation
CICS acts as a middleware layer between the operating system and application programs. It provides services like transaction management, data communication, and resource management, allowing applications to interact with system resources without dealing directly with OS complexities.
B
Correct answer
Explanation
In MRO, CICS regions cannot freely communicate with any other CICS - there are specific restrictions and configurations required. MRO enables communication between designated regions, not unrestricted communication between all CICS regions. This is why the statement is false.
-
indirect control
-
direct control
-
indirect and direct control
-
none of the above
B
Correct answer
Explanation
CICS (Customer Information Control System) is a direct control system. It manages online transaction processing and provides direct control over resources and transactions in IBM mainframe environments.
-
Many Important Selling Points
-
Meaningless Indicator of Processor Speed
-
Multiple Instructions Per Session
-
Million Instructions Per Second
D
Correct answer
Explanation
MIPS (Million Instructions Per Second) is a unit measuring processor performance by counting how many millions of instructions the CPU executes each second. It's a standard benchmark for comparing computer processing speeds, though its usefulness for real-world performance assessment is debated.
-
Domain and Node
-
Node and Domain
-
Grid and Node
-
Grid and Domain
B
Correct answer
Explanation
In Informatica PowerCenter, a Node represents the logical representation of a machine (server), while a Domain is a collection of such nodes managed together. This is the correct architectural relationship. Grid is a different concept related to load balancing.
B
Correct answer
Explanation
MP3 uses lossy compression, making files much smaller than uncompressed formats like WAV. AVI and VOB are video formats, not primarily audio formats. MP3 compression can reduce file size by 90-95% compared to WAV.
C
Correct answer
Explanation
JPG is an image file format (JPEG), not a video format. MP4, QT (QuickTime), and MOV are all video file extensions. This tests basic knowledge of file extensions.
-
Reposiitory Manager
-
Worklow Manager
-
Administration Console
-
Designer
A,C
Correct answer
Explanation
Repository Manager and Administration Console are both used for folder administration in Informatica PowerCenter. Repository Manager handles repository-level folder operations, while Administration Console provides broader administrative capabilities including folder management. Workflow Manager is for workflow design and Designer is for mapping transformations - neither handles folder administration.

Windows 3.1
-
Windows 95 Plus
-
Windows 95
-
windows 98
B
Correct answer
Explanation
Frosting was the internal codename for Windows 95 Plus, an enhanced edition with additional features, themes, and system utilities. Windows 3.1 used the codename Janus, and regular Windows 95 was Chicago.
